EXTENSIBLE FRAME.

Application filed February 12, 1923. Serial No. 618,705.

To all who-m t may concern.'

Be it known that I, JULES LEMERY, a citizen of the Republic of France,and residing at Dieppe, Seine Infrieure Department, No. 34:, Rue duGnral Chanzy, in the Re public of France, have invented certain new anduseful Extensible Frames, of which the following is a specification.

The present invention refers to an extensible frame which is principallyintended to allow the painters to show to their purchasers theirpaintings 'or pictures of different sizes suitably framed, without thenecessity Vfor them to incur the expenses or have the trouble of a largenumber of frames. The same can also be arranged so as to serve as anextensible framing to be used for maintaining in a stretched state thecanvas to be painted upon.

This extensible frame is composed of members or parts sliding the oneabove the other and of a small number of intermediate members which areused for filling up the empty spaces of variable length which are leftbetween the ends of the sliding members or parts.

The accompanying drawing shows by way of example several forms ofconstruction of a frame made according to the invention.

Fig. l is a `itront view of this frame, certain intermediate parts beingin position while some others have been removed.

Fig. 2 is a rear view thereof.

Fig. 3 is a section of same made according to line A-A of Fig. 1.

Fig. l is an elevation of a second form of construction of the frame,certain parts or members being broken away or removed.

Fig. 5 is an elevation Iof a third form of construction the intermediateparts being removed.

Fig. 6 is a cross section made, on a larger scale, according to line B-Bo'fFig. 5.

Fig. 7 is an elevation of a fourth form of frame, adapted to be used asa framing for stretching the canvas which is to be painted upon.

Fig. 8 is a cross section made according which are provided withcorresponding manner forinstance by means of screws 3 or simply by-meansof glue, etc.

Eachrear element on one side of the frame is rigidly secured to thefront element of one of the adjacent sides of the frame. The rearelement of each side of the frame is slidable upon the front element ofthe same side of the frame.

The members l andV 2 are suitably grooved 65 so that they may'be'able toslide longitudinally the one with reference tothe other, the memberl 1comprising' a groove l in which enters a corresponding tongue 5 of themember 2. 7O

These grooves and tongues can be dovetailed so that the members can betightly maintained the one against theY other. Furthermore, the guidingcan be obtained if necessary by means of slides made of metal or linedwith metal in order to secure a greater strength and an easier sliding,if deemed necessary. f

Moreover, each member l comprises a longitudinal mortise 6 in whichslides a bolt 7 secured to the corresponding member2;V nuts 8 allowy tomaintain the parts well pressed the one against the other in everyone'of the positions in which they have been placed. Si

Of course, this mode of fastening has been given by way of `exampleonly, and can be replaced by any other similar one.

In order to lill the empty spaces existing between the members, I makeuse of intermediate members or parts such as 9which are preferablyprovided with studs 10 and mortises or slots 11 so as to be perfectlyconnected at their ends with the members l a; slots or mortises andstuds.

Whereas 'there is a limited number of sizes of canvas currently used, itis only necessary to have a small number of intermediate members ofdifferent lengths in order to impart to the frame all the requiredsizes, as well to the height as to the width.

Fig. l shows the frame in front view, two intermediate members 9 beingin posi-V tion, the two others being removed.

Fig. 2 shows the back 40f the same frame.

Studs 12 and slots or mortises 13 can also be provided at the ends ofthe members l'.

It is obvious that the members 2 and the intermediate parts 9 can be ofany profile,l H" that the said members or parts can be gilt orornamented in any suitable manner.

vas to lill the intervals.

If necessary, the ornamentations-can be such that the joints of" themembers 2 and 9 will be concealed as well as possible.

In the form of construction which is shewn in the dnawings, the members2 and 9 are provided with a rabbet 1/1 into which the paintings larelocated.

According to Fig. 1, the frame comprises four angle-pieces which areL-shaped and the ends of which c're preferably cut Laccording toornamentallinesg-for exian'iple, as' shewn in the drawings so that ytheoints may be more easily concealed.

These parts 15 are connected' through straight parts 16 which are'situated at 'the rear part `of the fria-me andvcomplr'ise grooves 17 inwhich enter boltsff'l connected with the Iparts 15, the fastening being.obtained by means ofv nuts 8, as previously set forth. v

Intermediate members 9, bordered,- moulded, or ornamentedin the same wayasthe parts 15 are located between the latter so maintained for exampleby means of bolts 7 and nuts 8, like the previous" ones (which have notVbeen represented).

Projecting ornamentations 18 preferablyv cover" the joints so asl toVentirely conceal prlises aV front partA 19 and back part 2Ov rigidlyconnected together and for-'ming an angle piece, as in the pn'eviousforrmv of' con'- struction, but instead of -being mitered the ends ofthepart or 'member' 19 areV cut at right angle with reference tothedirection of the sides o-f the' frame, as shewn` in 21 and 22,' which ismore advantageous With reference to the perfectness of the jointsand thefacility of concealing the same.

The member 19 carries a bolt 7 which passes through a groove 6y ofthepart- 20 belonging to the following vangle of t-he frame, and these twoparts are guidedthe one above the other by means of strips or mouldings-23 located inthe grooves 24 of t-he part 2O and sliding in grooves 25 ofthe member 19. The fastening at the re' quired place is obtained bymeans of' nutsr 8' which are screwed upon the bolts-7. As' in theprevious case, the empty places'existing between the front parts 19 arefilled by intermediate members such asf26 lhavimg" the same section andthe same' ornamentation as themembers 19.

In order to' maintainV theseI members in position, it may beonlynecessary'tof provide These parts` are jection 28 tixedto the adjoiningpart 19, andl at the opposite end, a projection 29 entering into a slot30 of the corresponding part 19.

0f course, any other suitable fastening means can be use d for the samepurpose, for instance other bolts 7 and other nuts 8 similar to4 thosewhich secure the parts 19 to the parts 20.

The frame shewn4 in Figs. 7- and 8 differ from the one which liasfbeen`previouslydescribed in" that the parts or members` 19 and 20have atrapezoidal cross section in order to forma slightly dished frame sothatV the canvas to be painted upon which will be stretchedv over theframe and nailedy around its periphery will be solely supported by theridges 31 ofthe frame.

In order to avo-id the yielding of the long sides of the extensibleframev under the action of the tension of .the canvas it may be useful2to interpose between them crossties or stays the lengtlr of which can beadjusted; such a tie` can for example consist of a threaded irod orstenr 32 which freely slidesv ,in a tube 33 andy which carriesa nut Besoarranged? asf to bear against an end of this tirbe; the other end of thetube carries a studv 35I which enters one of the holes 36 provided' inone ofJ the members 2O while the external end of the rod 32 enters" oneof the holes 36 ofthe oppositeA part 20. It is only necessary to turnthe nut 34" in order'to modify, according to the requirements, thelength of the exten sible cross-tie which is-thus constituted.

The rear portions ofthe frame adapted. tov receive the tacks or nailsfor fixing the canvas vare preferably made of soft woorl oir lined withYsoft wood, While the front members 19 and 26Y can be made of yhard woodor lined with metal so as`- to insure the necessary rigidity andstrength.

Claim An extensible frame for paintings or pictures comprising L-shapedang-le parts. the two arms of each angle part being placed i-n twodiiiferent front and rear planes and being rigidly fixed the one againstthe other, means for Vguiding and fixing. the front arm o-f each anglepart to the rear arm of the following angle part, and intermediate partsof different lengths adapted to fill the variable empty spaces providedbe tween the iinont arms of the consecutive angle parts.

In testimony that I claim the foregoingl asmy invention, I have signedmy name in presence of two subscribing: witnesses.
